AUTOMATIC PAPER-FEED FOR PRlNTlNG-P RESSES.

SPECIFICATION forming part of Letters Patent No. 307,083, dated October28, 1884.

A pplication filed July To all whom it may concern:

Be it known that I, ANDREW R. BENNETT, of Utica, in the county of Oneidaand State of New York, have invented a new and Improved AutomaticPaper-Feed for Printing-Presses, of which the following is a full,clear, and etc act description.

The object of this invention is to devise practical means wherebyoscillating printing- Io presses may be made self-feeding.

The invention consists of sundry combina tions and arrangements ofparts, substantially as hereinafter fully set forth and claimed.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure 1 is an elevation of an ordinary Gordon oscillating printingpresshaving my invention applied thereto, the parts being shown in theposition they assume at the time the type are being inked by theinking-rollers. Fig. 2 is a sectional plan view of the same. Fig. 3 is asectional elevation showing the parts of the press and my improvementsin the position they assume at the time the impression is made. Fig. 4cis a detailed sectional side elevation showing the grippermovement. Fig.5 is an end elevation, partly 0 in section, of the support or box inwhich is placed the papers to be printed on. Fig. 6 is a detailed viewof a part of the feeding-arm and the pad, and Fig. 7 is a brokenperspective view of the winding-shell, for the dis 5 charging-web.

V A represents the reciprocating frame to which the feeding-arm B ispivoted. This feeding-arm B is provided at its forward end with thespring Z), and to the forward end of 0 this spring I) is attached, bythe screw 1)", the

pad I) of gelatine or other adhesive compound or material.

G represents thealischargingweb, for discharging the printed sheets fromthe platen P 5 of the printing-press.

D represents the cam for operating the grip pers G G.

F represents the support, having the ad- EZB, 1583. (No model.)

justable walls f and), for holding the paper 1) to be printed; and Hrepresents the box or receptacle having the guide-fingers 71 72, forreceiving the printed sheets from the discharging-web O.

The frame A is made pointed at one end, as shown in Fig. At this pointedend it is 5 5 provided with the friction-wheel a, which runs in agroove, a, formed in the inner surface and near the upper edge of theside plate J. The square end of the frame A has a groove formed in itsunder side, which fits upon a tongue, a formed upon the upper edge ofthe side plate J, and this frame A is connected by the connecting-rod Kand arm K to the ink-roller lever L, so that when this lever L isoperated from cog-wheel M, through 0011- necting-rod L, in the ordinarymanner the frame A will be reciprocated in and upon the said sideplates, J J. The feeding-arm Bis placed under the frame A, and ispivoted thereto at 0, (shown clearly in Fig. 3,) so that the feeding-armB reciprocates with the frame A, and the distance of movement of theframe A and the feeding-arm B may be regulated, as required for the sizeof the sheets of paper to be printed, by moving the forward end of theconnecting rod K in the slot k, made in the arm K, as will be understoodfrom Fig. 1,and the movement of the frame A should always be soregulated that when drawn to the limit of its forward movement theforward end of the feedingarm B will reach over the platen P to theposition shown in Fig. l for placing the sheets properly upon the platenunder the grippersG G, and when moved backward to the limit of itsmovement will carry the forward end of the S 5 feeding-arm B back of theplaten to the position shown in Fig. 3, so that the pad I) will comeover the pile p of blank paper placed upon the sup port F. The rear endof the feeding-arm B is provided with the friction-wheel I), and this isof such weight that it serves also as a counter-weight to the forwardend of the feeding-arm, so that normally the forward end of thefeeding-arm B will be held elevated in a plane with the under side ofthe frame A, as shown in Fig. 1.

Back of and in line with the feeding-arm B is held, in the cross-pieee(l, the backwardly inclined stud c. This is for the purpose-of causingthe forward end of the feeding-arm B to be depressed at the proper timeupon the pile of paper 1), for causing the pad I) to lift a sheet ofpaper, as illustrated in Figs. 3 and 4., ready for carrying it forwardover the platen P. r

In order tocause the feedingarm B to be again depressed at the end ofits forward movement for placing the sheet of paper upon the platen I, Iattach to the rear end of the feeding-arm 13 one end of the cord f, andthen pass this cord over the pulley 0, attached to the center of theframe A, and lead the cord from thence back and attach it to the stud c,as shown in Fig. 2, whereby, when the frame reaches the limit of itsforward movement, the cord will be so drawn upon by the action of thepulley c, as it recedes from the stud c, as to cause the cord to pullupon the rear end of thefeedingarln, which will have the effect todepress the forward end of said arm, and allow it to deposit upon theplaten its sheet of paper.

The grippers G- G are in all respects like the ordinary form ofgrippers, except that the slotted and pivoted bar G, to which they areattached, is formed or provided with the extension r to which isattached the crank y, by which the grippers are operated from the cam 1)through the medium of the bell-crank lever LT and connectingrod 0.(Shown clearly in Figs. 1, 3, and

The discharging-web 0 forms a close-iitting covering for the uppersurface of the platen 1 The web 0 is a foot and a half or two feet inlength. It is attached at its upper end to the winding roller or shellQ, which is journaled in the lugs it, formed upon or attached to theupper corners of the platen P, and at its lower end the web 0 isattached to th winding drum or shaft Q. The rolleror shell Q is madehollow, and is provided upon the inside with a spring arranged to actlike the spring in a balanced shade-roller for constantly holding theweb 0 taut over the surface of the platen 1, and for permitting it to bedrawn off by drum or shaft Q, as next described, for discharging theprinted sheets into the box or receptacle H.

The lower end or edge of the web 0 is, as above-stated, attached to andwound upon the winding drum or shaft Q, which is journaled below thelower edge of the platen l, as shown clearly in Fig. 3, and this shaft Qis provided at one end with the pinion j, which meshes with the rack It.This rack R is held in the frame S at the side of the press, and isformed at its rear end with the upwardly-projecting toe I, with whichthe wrist-pin m of the cogwheel M is adapted to engageas the cog-wheel Mrevolves for forcing the rack It forward in the frame S. This forwardmovement of the rack R will cause the pinion) and shaft Q to revolve atthe proper tin1ejust after each impressionand this revolution of theshaft Q, will draw the web G off from the shell Q and cause it to carryforward the printed sheet and drop it into the receptacle H. As soonasthe wrist-pin or shall have passed the toe Z, the spring within theshell- Q will act to wind the web 0 again upon the shell Q, as far asthe shaft or drum Q, will permit, and at the same time cause the rack 11to slide back to its original position. To assist this backward movementof the rack 1%, I provide the separate spring 8, placed in the frame S,which is compressed by the forward movement of the rack 1t, and reactsupon it as soon as the wrist-pin m passes the too i.

The box or receptacle H, for receiving the printed sheets, isheld in themain frame of the printing-press just below and in front of the platen1", and the arms 71- h,which are attached to the rear end of the box,reach up to and rest against the web (J, so as to receive and guide theprinted sheets from the web 0 into the box H, thus preventing all dangerof the sheets being drawn under the press by the movement of the web 0.

The support F for the paper 1) is held be tween the side plates, J J, bythe screws 0 0. Upon its under side this support F is pro vided wit-l1the dovetailed cleats t '1, between which the bevel-edged arm t oftherearboard,

f", fits for holding the said board in position for holding the pile ofpaper p, as shown in Fig. 3.

In the upper surface of the support F are formed what are designed to bedovetailed grooves a n, (shown clearly in Fig. 5,) in which grooves theheads 6 z" of the bolts 6 cfit, said heads inpractice being beveled toconform to the surface of the groove. These bolts pass through thebracket-pieces 1; o, and these bracket-pieces are attached to the sideboards, ff, which side boards serve to hold the pile ofblank paper pfrom sidewise movement upon the support F, as will be understood fromFigs. 2 and 5. The side boards, ff, by loosening the thumb-nuts c o ofthe bolts (1 0, may be adjusted upon the support F to suit the size ofthe sheet of paper to be printed, and the rear board, f may also bemoved between the cleats t t to suit the size of the paper 1) to beprinted. V

In operation, a blank sheet being in place upon the web 0 on the platenfl, and held by the grippers G G as theinking-roller lever L is drawnforward by the eog-wheel l\[ and connectingrod L, for carrying theinkingrollers T upon the ink-plate T, the frame A and feeding-arm B willbe forced backward upon the side pieces, J J, by the action of the armsK and connecting-rod K, which movement will bring the rear end of thearm 13 against the stud 0, which will cause the forward end of the arm13 to be depressed and bring the adhesive pad 1) down upon the pile ofpaper 1), as shown in Fig. 3. In the meantime the platen P will havebeen raised by the action of the arms U of the press and the impressionof the type, held upon the bed V of ICO ITO

printed sheet into the box H.

the press, taken, the upward movement of the delivery-web 0 (resultingfrom the difference in the arcs described in the movements of the weband platen, due to the different locations of the pivotal point oftheplaten and the lower web-cylinder) being prevented from displacingthe paper by reason of the holding action of the grippers exerted uponthe paper. Now, upon the backward movement of the lever L for bringingthe inking-rollers Tover the bed V for inking the type, the platen 1will descend to receive the next blank sheet. At this time thegripper-arms G G, through the action of cam I), bell-crank lever N,extension g, and crank y, will be raised off from the sheet justprinted. By this time the wristpin at will have reached the toe Z of therack B, so that the further revolution of the cogwheel M will move therack It forward, which will cause the drum or shaft Q to revolve, whichwill draw the web 0 off from the winding-shell Q and cause the web todischarge the The wrist-pin at now having passed the toe l, thespring-aetuated-shell Q will act to return the web 0, and also, togetherwith the springs s, to return the rack R and drum or shaft Q lVhilethese operations of the web, ripper, platen, &c., are beingaccomplished, the arm K and c011- neetingrod K will have begun to drawthe frame A and feeding-arm B forward with a continuous movement. Uponleaving the stud e the weight of roller b will cause the forward end ofthe feeding-arm B to be lifted,

which, owing to the adhesivencss of the pad b, will lift a sheet of thepaper off from the pile p, and, the forward movement of the frame A andarm B continuing, this lifted sheet will be carried by the feeding-armover the platen l? and under the grip 'ier'arms G G. The sheet havingreached the proper point, the gripperarms will again be operated asabove stated, causing them to grasp theblank sheet of paper and hold itupon the web 0 and platen P. Now, the lever L will again be drawnforward by cog-wheel M and connecting-rod L, and

the frame A and feeding-arm B will again be forced backward by arm K andconnectingrod K, and the platen P will again be raised to print thesheet now held upon it by the grippers G G, and this having been donethe parts will repeat the motions just described, and all of the motionsdescribed will be re peated with the printing of each sheet. In thismanner it will be seen that the feeding of the press is entirelyself-acting, so that the press requires no attention but to supply itwith the blank sheets in a pile.

Having thus described my in vention, I claim as new and desire to secureby Letters Patent.-
